Math review / tutorial

for those of you that might be struggling with algebra or trig in your chemistry or physics classes or even currently taking algebra or pre-calc, this looks like a pretty good tutorial / review site - I glanced at some of the trig topics (e.g. Law of cosines, radian measurement, etc.) and it seems pretty well done.

Thanks for posting this! I'll have to check it out since I'm PreCalc now. The Trig component is next semester…
